Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable terminal device that performs control to turn on or off a power according to a user's usage situation.
[0002]
[Prior art]
Mobile terminal devices have become widespread, and individuals have mobile phones. Since the mobile phone is used for wireless communication, it is necessary for the mobile terminal device to make an incoming call determination with respect to its own mobile terminal from the terminal itself to the base station at regular time intervals.
[0003]
For this reason, the portable terminal device has an intermittent control function, enters a sleep state for a certain time interval, and powers off the non-functional LSI. Then, after a predetermined time has elapsed, the LSI is powered on, processing is started, and incoming call determination is performed. If there is no incoming call, it goes to sleep again. Thereafter, the same operation is repeated.
[0004]
On the other hand, if there is an incoming call to its own terminal, the control shifts to reception processing after the incoming call determination.
[0005]
In the above case, the intermittent control function in the portable terminal device is operating even in a time zone where there is no incoming call such as at night or a time zone where it is not used at all.
[0006]
As a conventional example, a digital mobile phone device capable of stopping power supply to as many circuits as possible within a predetermined period in which no data is transmitted and received and supplying a symbol clock signal in the same phase as before when restarting the circuit. (For example, refer to Patent Document 1). In addition, there is a mobile phone that can save power by setting a user without depending on a reception environment or an operation interruption state (see, for example, Patent Document 2). There is also a communication terminal device that consumes power in the standby state and informs the user of the standby state (see, for example, Patent Document 3).

[Problems to be solved by the invention]
However, in the portable terminal device, the incoming call determination is performed while performing intermittent control. However, in the case of the conventional configuration, the intermittent control circuit still operates inside the portable terminal, so that the standby time is improved. It's getting harder.
[0009]
Further, the communication terminal devices described in Patent Documents 1 and 3 which are the above-described conventional examples can reduce the power consumption during standby, but cannot completely turn off the power, and the power on -It does not automatically switch off. In addition, the mobile phone described in Patent Document 2 requires a user's own operation to set an on / off time in advance, which is not convenient.

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0018]
First, the overall configuration will be described with reference to FIG. FIG. 1 is an overall block diagram showing an embodiment of the present invention. The CPU 11 includes a power ON / OFF circuit 12 that performs power ON / OFF control, a control circuit 13 that performs intermittent control, a baseband LSI 14, a radio unit TRX 15, an antenna 16, a buffer 17, and a POWER control circuit 18. The CPU 11, the power ON / OFF circuit 12, and the control circuit 13 are responsible for intermittent control of the baseband LSI 14, the radio unit TRX 15, and the POWER control circuit 18.
[0019]
The CPU 11 controls the power ON / OFF circuit 12 and the control circuit 13 with software. Then, the baseband LSI 14, the radio unit TRX 15, and the POWER control circuit 18 are intermittently controlled via the control circuit 13. The power ON / OFF circuit 12 turns ON / OFF this intermittent control. In the buffer 17, a control program is saved.
[0020]
FIG. 2 is a configuration diagram of the power ON / OFF circuit 12. The timer X24 is a timer that counts the current time. The register X21 is a register in which the time to turn off the power is saved. The comparator X22 compares the two, outputs a signal at the same time, operates the interval circuit 23, and disables the control circuit 13 at the subsequent stage.
[0021]
The register Y26 is a register in which the time to turn on the power is saved. The comparator Y25 compares the two, outputs a signal when the same time comes, stops the interval operation of the interval circuit 23, and starts the control circuit 13 in the subsequent stage.
[0022]
The interval circuit 23 has a function of turning off the power for a certain time and a function of turning on the power for a certain time.
[0023]
A table 27 serves as a reference for setting the time for operating the interval circuit 23. In this table 27, the power-off time set by the user or the power-on time is saved. Further, the time when the power is turned off or the time when the power is turned on is saved according to the result determined from the user's incoming call determination described later.
[0024]
FIG. 3 is a diagram illustrating a configuration of the control circuit 13. The control circuit 13 is provided with timers B31 and C34. These two timers count stop time (sleep time) and start-up time, respectively. Timer B31 and timer C34 operate sequentially.
[0025]
That is, the comparator B33 performs comparison with the register B32 while the timer B31 is in operation, and the timer C34 starts after matching. While the timer C34 is operating, a comparison with the register C35 is performed by the comparator C36, and a control pulse is output after the comparison.
[0026]
By mounting a plurality of combinations of the register C35 and the comparator C36, a plurality of control pulses can be output. That is, it is only necessary to add registers and comparators for the necessary signal types.
[0027]
FIG. 4 is a flow showing a procedure for counting incoming histories. In a normal mobile terminal device, the incoming call determination process is repeated while the user does not perform any operation. Intermittent control is used for this incoming call determination. The intermittent control includes a sleep time and an incoming call processing time. During the incoming call processing time, the LSI mounted in the mobile terminal device is activated, a signal from the base station is received, and it is determined whether there is an incoming call to the mobile terminal device.
[0028]
On the other hand, the sleep time is a time period in which only a minimum necessary device operates and a device that does not have to operate now is in a stopped state. It is determined whether there is an incoming call in the incoming call determination in which the process is repeated by the intermittent control.
[0029]
If there is no incoming call (S101 / NO), the incoming call determination is repeated at regular time intervals. If there is an incoming call determination (S101 / YES), the process proceeds to incoming call processing, but the incoming call history is recorded before that (S102). Then, before the incoming call processing, the count value of the time table is counted up from the current time information (S103). Then, the distinction of whether there is an incoming call or not is totaled for each unit time. Here, the time zone without incoming call determination relates to the set time of the ON / OFF control circuit of the control circuit described later.
[0030]
FIG. 5 is a table for setting a timer time for ON / OFF control, and shows an example of a table for calculating an incoming history for each time zone. As shown in FIG. 5, the incoming call history is recorded every hour. The incoming call history is recorded according to the flow shown in FIG. Then, it is determined whether there is an incoming call or not for each time period. If there is an incoming call at this table, no special action is taken. If there is a time zone in which there is no incoming call determination, the time for turning off the power and the time for turning on the power are set in the register X21 and the register Y20 from the table 27, respectively.
[0031]
The case shown in FIG. 5 is a table showing a tabulation table when there is no incoming call from 1 am to 6 am. FIG. 5 is an example of setting. In other words, depending on the function of the terminal model, a more detailed control is possible if the incoming call history counting method is further shortened, for example, in units of 30 minutes.
[0032]
The mobile terminal device of the present invention always counts incoming histories. The history is totaled for each predetermined time zone, and it is determined whether there is an incoming call. From this result, it is possible to automatically turn off the mobile terminal device when the time zone comes, and to turn on the mobile terminal device when the time comes. A clock function is necessary to operate these functions. However, since the portable terminal device of the present invention has a clock function, the clock function is used to train table data and ON / OFF control can be performed. However, this does not apply when the other party is called by himself or when there is an interrupt from another LSI.
[0033]
FIG. 6 is a timing chart showing the overall operation. A signal output from the ON / OFF control circuit is a control signal. By this control signal, the control circuit of the next stage is operated or stopped. This control signal turns the power on or turns the power off.
[0034]
Here, as shown in FIG. 5, a timing chart in the case of controlling based on the result of totaling and calculating the user's incoming histories is shown. That is, according to the result of the table, at 1 am, the control signal output from the ON / OFF control circuit becomes inactive, and the control circuit is stopped.
[0035]
At this time, intermittent control is also stopped simultaneously. At 6 am, the control signal output from the ON / OFF control circuit becomes active, the control circuit is operated, and the operation of the intermittent control circuit is resumed.
[0036]
【The invention's effect】
